Solution Overview

Problem

Existing applicators for self-adhesive cleaning products are complex, require two-handed operation, and have exposed mechanisms that can be accidentally activated, leading to inconsistent dosing and potential product leakage.

Innovation Solution

A device with an internal staggering mechanism, comprising a doser and applicator with internal projections for guided dosing, a plunger for controlled expulsion, and a protective cap for safety, allowing single-handed operation and precise fractioned dosing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If an exposed staggering mechanism is used for dosing, then the device can dispense product, but the mechanism can be accidentally activated and dosing becomes inconsistent

Engineering Contradiction:
Improvedosing consistencyVSAvoidaccidental activation risk
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent applies nesting by placing the staggering mechanism inside the applicator body rather than exposing it externally. The dosing element is nested within the protective housing, accessible only through a controlled interface, preventing accidental activation while maintaining dosing functionality. This internal configuration ensures that only intentional user actions can trigger product dispensing.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Quantity of substance

If a complex dosing mechanism is used, then fractioned dosing can be achieved, but the device structure becomes complex and requires two-handed operation

Engineering Contradiction:
Improvefractioned dosing capabilityVSAvoidmechanism complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent segments the dosing mechanism into distinct functional elements: a dosing element with defined chambers for fractioned dosing, a plunger for actuation, and a staggering mechanism for controlled dispensing. Each segment performs a specific function, allowing complex dosing capabilities to be achieved through simple, modular components that can be operated with one hand.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent extracts the complex dosing mechanism from traditional external configurations and integrates it into the internal structure of the applicator. The dosing chambers, plunger, and staggering elements are all contained within the applicator body, removing the need for external complex mechanisms and enabling single-handed operation while maintaining fractioned dosing capability.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of operation

If the applicator is designed for single-handed operation, then ease of use improves, but control over the dosing mechanism becomes difficult

Engineering Contradiction:
Improvesingle-handed operationVSAvoiddosing control
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent merges the dosing control functions into a single integrated plunger mechanism that performs multiple actions: advancing the staggering element, controlling product flow, and actuating the dosing chambers. This unified mechanism can be operated with one hand while maintaining precise control over the dosing process, as all critical functions are combined in one actuation point.

Inventive Principle:
Principle #5Merging (Combining)
